Before-and-After Look at Impact Craters Figure B
October 19, 2009
Figures A and B: The first two figures show sub-frames of an image acquired on March 13, 2006. The first one has been colorized using a table derived from the colors of Mars as seen by the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment camera. The impact site is located near 27.3 degrees north latitude, 91.8 degrees west longitude, on the upper north flank of the Martian volcano Ulysses Patera. Fine details are evident at the impact site, showing how the blast moved dust around and interacted with craters and other small obstacles on the ground. The crater has a diameter of about 19.8 meters (about 65 feet).
